不同山药种质资源的腺苷含量比较研究

ADENOSINE CONTENTS IN DIOSCOREA OPPOSITA THUNB. OF VARIOUS GERMPLASM RESOURCES: A COMPARATIVE STUDY

目的为了解山药资源腺苷含量情况,进一步对该部分资源的腺苷含量进行分析。方法采用高效液相色谱法测定不同种质资源山药腺苷含量。结果不同种质薯蓣腺苷含量差异极显著,其中腺苷含量最高的是山东兖州的山药(0.199%);最低是河南焦作的山药(0.019%);总平均含量为0.095%。结论不同种质来源的山药腺苷含量差异较大,提示临床用药应注意不同种质来源,同时也为薯蓣的引种提供依据。

Objective：To investigate the adenosine contents in Dioscorea posita Thunb. of various germplasm resources. Methods： Adenosine contents in D. posita of various germplasm resources were determined using high-performance liquid chromatography. Results： Significant differences among various germplasm resources of D. postita were observed, the highest adenosine content of 0.199% was determined in the sample from Yanzhou, Shandong province, whereas the lowest（0.019%） from Jiaozuo, Henan province. The average adenosine content was 0.095% of the above samples. Conclusion： There were significant differences in adenosine contents of D. posita among various germplasm resources, which prompted the attention should be paid to in clinical treatment based on the resource differences and provided theoretical basis for the introduction of D. posita.
